ABSTRACT

Apparatus and process for the production of stranded wire from copper wire, whereby the stranded wire is wound upon a spool by means of a transfer mechanism. A control arrangement is provided, which regulates the rotation of the spool, the motion of a transfer element which is a component of a transfer mechanism and a separate drive for the transfer mechanism.

FIELD OF THE INVENTION

The present invention concerns an apparatus for the production ofstranded copper wire and the like. Further the invention is in regard toa procedure for the control of an apparatus for the production ofstranded wire and the like.

BACKGROUND OF THE INVENTION

For the manufacture of flexible, electrical conductors, such as findapplication in all branches of industry, normally copper wires ofrelatively small diameter are worked into a strand, which is thencovered with an electrical insulating material. The production of thisstranded wire is done generally in a double stroke stranding machine.The invention will on this account be described in relation to a doublestroke stranding machine. However, notice is given that the applicationof the invention is not limited solely to a double stroke strandingmachine, but finds application with other, similarly operating strandingand cable machines. In addition, the invention is also employed to workmaterials which are not copper into a flexible stranded or similarstranded object.

An apparatus for the production of stranded wire in accord with thegeneric preamble portion of the independent apparatus claim 1 has beenmade known by the DE 35 00 949 C2. In the case of this arrangement,which is designed as a double stroke stranding machine, is found a rotorwith two yokes, which is so swivelably mounted, that it is able torotate itself about a horizontal axis. The rotor is driven by a motor.Within the rotor a spool carrier is mounted, on which a spool isturnably set. This spool is put into rotation by a second motor, whichis placed outside of the rotor. The turning power of the motor istransmitted to the spool by a gear drive. The finished stranded wire iswound on this spool. For the removal of the spool, a displacementapparatus is employed, which possesses a threaded spindle, which isinstalled parallel to the rotating axis of the spool. A transfermechanism, normally a transfer element directs the finished strandedwire on to the spool and as it does so, runs back and forth parallel tothe spool axis so that the stranded wire is wound evenly on the spool.The drive of the transfer apparatus is kinematically coupled firmly withthe rotating movement of the spool, so that a given RPM of the spoolcalls forth a corresponding linear displacement of the transfer element.

From EP 0 563 905 A1, an additional arrangement for the making ofstranded wire is made known, wherein inside the rotor, a winding spoolis employed, the rotating axis of which is installed transverse to thatof the rotor. Even in this case a transfer apparatus is provided whichis kinematically coupled with the rotary movement of the winding spool.

Although these conventional apparatuses operate very satisfactorily, theproblem frequently arises, that the end product, which is comprised ofthe spool and the stranded wire wound thereon does not sufficiently meetthe demands of subsequent handling.

Further, there is another problem in that it is difficult to bring aspecified length of stranded wire onto the spool. This is especially adisadvantage, since the stranded wire is often reworked along with otherstranded wire and this subsequent treatment must be interrupted when thespool, which has the shortest stranded wire is fully unwound. Theresidual length of stranded wire on the other spool must then be woundoff and disposed of as waste material.

SUMMARY OF THE INVENTION

Thus, it is the purpose of the present invention to create an apparatusfor and to provide a process for the making of stranded wire whichimproves the possibility of subsequent operations thereon.

This purpose will be achieved in accord with the invention by means ofthe substance of the claims.

Preferred extensions and improvements of the invention are subjects ofthe subordinate claims.

The invention proposes to provide the transfer apparatus with a separatedrive mechanism, which will supplant the customary kinematic couplingbetween the rotary movement and the spool as well as the translationalmotion of the transfer element. Further, the invention proposes tocapture the rotary motion of the spool by an RPM pickup and forward thissignal to a control device. This control arrangement exhibits a programstorage in which one or more programs are stored, according to which thetransfer element can be controlled in accordance with the rotary motionof the spool.

The achievement of the purpose in accord with the invention offerssubstantial advantages as opposed to the known apparatuses of thepresent state of the technology. In the case of the known apparatuses,the transfer element runs in hard, kinematic coupling parallel to theaxis of rotation of the spool. In this way, the wrapping pattern of thewinding which is to be brought onto the spool is determined beforehand,so that only continuous layers, parallel to the cylinder axis can bewound.

By means of the configuration in the terms of the invention, it willbecome possible for the user to bring about optional wrapping pattern onthe spool, so that the spool can be wound in such a way as to be optimalfor the carrying out of further rework. Beyond this, the user of theknown stranding machines is compelled to use spools in which the spoolcore, upon which the windings are to be laid, is cylindrically shaped.

In fact, cylindrical spools for rework operations are oftendisadvantageous. On this account, spools are often used as a matter ofcourse in the present technology which have a conical wrapping core or,at least in some cases, a flange which exhibits a self extending,conical inside flange surface. Rework using such spools is not possiblewith conventional equipment.

In the case of the equipment in accord with the invention, the user canoptionally choose the shape of the spool, insofar as it conforms to thegeneral dimensioning of the machine. The program, with which thetransfer equipment is controlled, can be adapted in a very simple mannerto the given spool shape, so that the manufacturer can cover all optionsin regard to the spool shape.

The transfer element, moreover, can be so controlled that on thedifferent spools a different winding pattern can be achieved to meetcurrent requirements of the user. Thereby, the individual wishes of theuser can be given more attention . In addition, the use of individualwinding patterns permits the complete filling of spools, which nocylindrical wrapping core, that is to say, conical flange can show.

The achievement of the purpose in accord with the invention has yetadvantages in regard to the exactness with which a defined length of thestranded wire can be brought upon the spool. In the case of conventionalequipment, it is necessary, that the spool , after reaching a specificlength, is still further rotated until the transfer mechanism reaches adefinite position which is appropriate for change of spools. From this,additional lengths are wound on the spool which, in many cases, must beremoved from further rework to be disposed of as scrap. With thesolution as proposed by the invention, it is possible to so adjust thecontrol of the transfer mechanism, that upon reaching a specifiedstranded wire length, it moves itself to a position advantageous forspool change, without the spool itself rotating any further.

The apparatus in accord with the invention exhibits a sensor element, inorder to capture the RPM of the spool. The signal delivered from thissensor serves as input for the control.

Advantageously, the momentary position of the transfer element islikewise determined and is input to the control unit as an additionalvalue. Through this, the control receives the character of a closed loopcontrol circuit. If the movement of the transfer element is effected bymeans of a threaded spindle, as is known in the present state of thetechnology, then also the momentary position of the transfer element canbe determined by an RPM sensor, which counts the angle of rotation ofthe threaded spindle from a given null position. In this case aconventional motor can be used for the drive of the transfer element.The motor's speed of rotation will be controlled in dependency of theinput values by the said program.

In a preferred embodiment of the invention, the motion of the transferelement is controlled by means of a stepping motor. In this case,advantageously, a threaded spindle is used, by means of which thetransfer element is driven. The history of steps taken by the motor atany given time are stored in the control equipment, so that the controlcan compute at that point in the actual position of the transferelement.

Digressing from the above method, it is also possible to employ sensorswhich determine instantly the travel of the transfer element along aguide bar or the like.

In the case of a further embodiment to be preferred, the transferelement is activated by a linear stepping motor, whereby the actualposition of the transfer element again becomes known from the number ofthe steps which have been taken.

Besides the above named sensors, that is, rotating or lineal steppingmotors, sensors can be arranged advantageously which send a signal whenthe transfer element touches the first or second spool flange.Advantageously, one of these end points is a reference point, so thatupon contact with this sensor, simultaneously also the null point forthe stepping motor is defined.

The control equipment, in a first embodiment, is installed outside theactual stranding machine, that is, in a customary switching cabinet. Inthis embodiment, however, means must be provided to pick up the signalsfrom the rotating components of the machine. For instance, this can bedone with commercially available slip ring transmission or a mercuryswitch.

In accord with an especially preferred arrangement, the controlequipment is provided directly on the spool carrier. Since the spoolcarrier itself undergoes no rotary motion, all sensors can be hardwiredto the control facility.

The source of current in this case must be brought in over slip ringsfor the control equipment and drive mechanisms of the stranding machine,etc. Although relatively high demands are to be placed on the quality ofthe signal transmission in the case of data transmission, smalldisturbances in the transmission of the supply voltage will have noinfluence on the function.

The problems of the transmission of the control and measurement signalscan also be solved, in that the transmission is done without wiredconnection from a sensor/receiver unit outside the machine to asender/receiver unit inside the machine. In this case, the measurementsare preferably transmitted in digital form, whereby a known modulationprocedure is used, as is known in the present state of the technology,for instance, amplitude modulation or frequency modulation. In order tomake the transmission of the measured values reliable and secure, thesend/receive units are to be so made, that before and after eachtransmission of measurement and control values, a monitoring code willbe included. Signals will then only be evaluated by the receivingequipment functional at the time, if the control code is identical to agiven control code. The transmission of the signal can also beaccomplished without hardwiring by using ultra sound, infra red, orelectromagnetic waves (radio waves).

As has been explained above, the equipment in accord with the inventionallows the spool to be changed without interfering with the transferelement, as soon as a predetermined length of stranded wire has beenwound on the spool. In order to increase the exactness of the length ofthe already wound stranded wire, the invention proposes in addition,that the transfer element have a transfer pulley, or a component withseveral pulleys, and that the length of the stranded wire is deriveddirectly from the angle of rotation, i.e. the number of revolutions ofthese rolls. In this case an additional sensor is provided for thecontrol equipment, which counts the-revolutions of at least one of thepulleys of the transfer element and sends a corresponding signal to thecontrol equipment.

In the present state of the technology, for the transmission of thestranded wire lengths, sets of rolls were employed, which were setbefore the entry of the corresponding bundle of wires into the strandingmachine. However, since the length of the finished stranded wire variesa few per cent, for instance, 2 to 3%, from the length of the incomingbundle of wires, there is thus no precise determination of the length ofthe finished stranded wire possible. Due to the fact that the angle ofrotation of a pulley of the transfer element can be captured, so thelength of the stranded wire be very accurately determined, and thus themaking of scrap diminished.

DETAILED DESCRIPTION AND PREFERRED EMBODIMENT

The invention will now be described in detail with the use of anembodiment example. In this embodiment the apparatus, in accord with theinvention, is presented as a double stroke stranding machine. Since theprincipal design and the function of a double stroke stranding machineis known in the state of the technology, cognizance will only be takenof such parts as are of consequence in regard to the invention. For theconstruction and the function of a double stroke stranding machine,amongothers, the following references are given, first, to the mentioned DE35 00 949 C2 and second to the EP 0 563 905 A1, declarations of both, bymeans of this reference, are herewith made a part of this declaration ofthe present invention.

The rotor 2, which, in this embodiment, possesses two yokes (nodesignation number) is swivelably mounted in the machine framing 1 ofthe depicted double stroke, stranding machine. The rotor 2 is driven bya motor 3. The drive of the motor is transmitted by means of a (notshown in FIG. 1) flat belt drive.

In rotor 2, a spool carrier 4 is secured in a rotatable manner. Thespool carrier exhibits two carrier side pieces, 6 and 7, in which thewinding spool 10 is set in bearings for rotation.

In the case of the presentation of FIGS. 1 and 2, is drawn a windingspool, which consists of a cylindrical winding core 11 wherein thecylinder axle is, at the same time, also the rotational axle of thespool which has two disk shaped flanges 12, 13 placed on the ends of thecylindrical core. The meaning of "disk shaped" is, that the flanges 12,13 show themselves as a flat surface disposed vertically to therotational axis of the winding core 11. This planar surface, on bothends of the said axle, faces the winding space in which the finishedstranding will be wound.

Although, in the double stroke stranding machine, in accord with the DE35 00 949 C2, the rotational axis of the winding spool lies parallel tothe rotational axis of the rotor, the rotational axis of the windingspool in the example embodiment, in accord with FIGS. 1 and 2, isarranged transverse to the rotational axis of the rotor. Constructionwith parallel axes, however, is likewise possible.

The winding spool is driven by a motor and rotated, in order to wind thestranded wire.

As may be inferred from FIG. 2, a transfer mechanism 20 is provided,which (see FIG. 4) has two guide bars, 21, 22 parallel to each other bymeans of which a transfer element 24 is run parallel to the longitudinalaxis of the winding spool 10.

The transfer arrangement is made fast to the side pieces 6, 7 of thespool carrier and is thereby secured in its spatial position relative tothe spool carrier and to the winding spool.

The transfer element 24 is longitudinally movable with a sliding seat 26along the cylindrical guide bar 21.

The second guide bar 22 is made as a threaded spindle, and rotatablewith ball bearings 27, 28 in the spool carrier and, by means of aspindle nut 30, connected with the transfer element 24. The spindle nut30 operates in such a way, that the transfer element 24 slides in alongitudinal manner along the threaded spindle 22, when this threadedspindle is set in rotation.

The drive of the threaded spindle 22 is effected by a stepping motor 32.A gear 35 is placed on the output shaft 33 of said motor. The rotarymotion of this gear 35 is transmitted by means of a toothed belt 36 to agear 37, which, by means of an adjusting spring 39, is affixed in amutually rotating manner to the threaded spindle 22.

Affixed to the transfer element are one or more transfer pulleys, whichare not presented in FIGS. 3 and 4. The stranding is run over thesesupplementary transfer pulleys. An example of such a transfer pulley isshown in FIG. 5, in which depicts how the stranded wire "L" runs to thewinding spool over a first pulley 42 and a second pulley 43, which arealways rotatably set in bearings. (Winding spool is not shown in FIG. 5,see FIG. 1).

On a bar 50, which is installed parallel to the guide rod 21 andthreaded spindle 22, there is provided a first 52 and a second 53 limitswitch. These limit switches emit an electrical signal, as soon aseither of the protruding contact making devices 55 on the transferelement 24 comes into contact with one of the limit switches.

FIG. 6 shows a first example of the control equipment, by which thedouble stroke stranding machine here described is regulated.

The control equipment, which is designated overall with the referencenumber 60, shows a first control module 61 and a second control module62.

The first control module 61 is correlated to a first memory storage unit63 and the second control module 62 is correlated to a second memorystorage unit 64. Both storage units are provided to store programs anddata.

The first control unit 61, by means of an interface 70, is connected toa series of sensors, whereby the first sensor 71 sends a signalrepresentative of the RPM of the winding spool to the interface, whilethe second sensor 72 sends a signal which is emitted by the limit switch52 of the transfer mechanism, the third sensor 73 sends a signal whichcomes from the limit switch 53 of the transfer mechanism and the fourthsensor 74 provides a signal, which corresponds to the count ofrevolutions of a pulley of the transfer mechanism.

In this control example, the first control module 61 is affixed to thespool carrier and, on this account, can be connected with the interface70 and thereby to the individual sensors by wire connections, which arerepresented by solid lines.

The emitted control signals from the first control module 61 aretransmitted over an interface 80 to the stepping motor 32 and a (notshown) spool clamp-in and exchange device.

The second control module 62 is mounted stationary on the machineframing 1 of the double stroke stranding machine, and receives signalsfrom various sensors, of which, as an example, the signal from thesensor 76, which provides the RPM of the rotor, as is made plain in FIG.6.

The control unit 62 sends out control signals over interface 82, which,for example, are conducted to the drive motor of the rotor and the drivemotor of the winding spool. If the winding motor is directly correlatedto the spool carrier, then its control signal is led over the interface80 and the control module 61.

The connection between the control module 61 and the control module 62is made by means of slip rings, as is indicated by the dotted line.

The function of this example of one arrangement in connection with FIG.1 is as follows: At the beginning of production, or following the startof an empty spool in the spool carrier, the transfer element of thetransfer mechanism is found in an end position of its back and forthlinear travel. This will be indicated by the closing of the contacts ofone of the limits switches, i.e. E1 or E2. The rotation counter for thetransfer pulley 74 is set at zero. The motors M1 and M2 are started andthe production and the winding of the stranded wire begins. The controlmodule 61 issues the corresponding chosen program from the memorystorage bank 63 to the stepping motor 32, whereby the transfer element24 is moved parallel to the rotational axis of the spool. In thisaction, the RPM of the spool and the movement of the transfer elementare so correlated with each other, that a prespecified winding patternarises, which is chosen in agreement with the requirements of the reworkprocedure and especially in accord with the shape of the winding spool.During the continuing operation of the winding, the control module 61can compute, at any time the position of the transfer element, whichcomputation is made on the basis of the exchange of signals as aboveindicated. In order to establish a definite winding pattern, during thetransfer procedure, the end points at which the transfer elementreverses its travel, accordingly alters the control signals of theprogram. Thereby, winding layers are made , the length of which (as seenparallel to the rotational axis of the spool) is different. At the sametime, or independently therefrom, the pitch of the wound layers, thatis, the spacing of side by side windings to one another, can be changed.

The making of the stranded wire, and its laying on the spool will becarried on until such a time that a predetermined quantity of strand iswound on the spool. This predetermined quantity of stranding isspecified by the program from the number of revolutions of the transferpulley. As soon as the predetermined quantity of stranding is wound, themachine is stopped and the transfer element run by the stepping motor toits appropriate end position for spool exchange. The spool is thenlifted out of the spool carrier by a spool changer apparatus, as isdescribed in the EP 0 563 905 A1 and replaced by a new empty spool.

The described control equipment as depicted in FIG. 6 has the advantage,that the control unit 61 is itself affixed to the spool carrier. By thismeans, the signals of the single sensors, and those signals directed tothe stepping motor and the equipment of the spool change apparatus canbe transmitted through hardwire connections. It is basically required,that the current feed is made over slip rings.

The data exchange between the control module 61 and the control module62 is limited to a low volume of data which is necessary for the controland the stranding machine. These data can be sent in a very simplemanner over slip rings.

In another alternative to the embodiment example in accord with FIG. 6,the RPM of the rotor can also be captured with a sensor which is mountedon the spool carrier. In the case of this variant, the controller module61 receives all the relevant data for the control of the transfermechanism directly through sensors, which are hard wired to said controlunit 61.

Through this design, a very reliable operation is achieved. moreover,the construction is also very much simplified.

Yet another construction for the control equipment is to be seen in FIG.7 and is described in the following. This control arrangement is, in thesame manner as above, adaptable to be used with the embodiment as shownin FIGS. 1 to 5. The same, or principally the same parts are defined bythe same symbols and reference numbers as were used in FIG. 6.

In this embodiment example, a central control module 85 is used with astorage 86 for memory, all of which is mounted stationary on the machineframe.

The connection to the sensors 71, 72, 73 and 74 which are mounted on thespool carrier is made through interface 88, and in a first variant ofthis embodiment example, this is done through slip rings or mercurycentrifugal switches. In a corresponding manner, the signals to thestepping motor 32 and to the spool exchange apparatus are transmittedover slip rings or similar connection means 90 for rotating members.

This embodiment example possesses the advantage that the construction ofthe control module 85 is in many ways, simplified. A disadvantage,however, is that a relatively higher cost is required in order totransmit data from the sensors to the interface 88.

The application of rotary connecting means of this type has thedisadvantage that in the case of lower priced rotary connection means,the quality of the transmission is not always reliable, while the use ofreliable sensors leads to very high expense. In a further variant, whichis usable as well in connection with the embodiment example in FIG. 6 aswell as with the embodiment example in accord with FIG. 7, the inventionproposes on this account, to effect the transmission of the data withoutwiring. In this case the data, insofar as they are not alreadydigitalized, are advantageously digitally keyed, which can be donethrough a change in frequency, amplitude or the phase situation of acarrier signal. Carrier signals can be, for instance, ultra sonics,infra red signals, or most especially electromagnetic (radio) waves.

A wireless transmission can be employed in such a manner, that, in thecase of the embodiment example in FIG. 7, the values of the individualsensors can be sent directly to interface 88, preferably by theinsertion of yet another interface (not shown in FIG. 7). Received ininterface 88, the signals are there demodulated and subsequently sent tothe control module 85 as digital signals.

The transmission without wires can be particularly preferred when usedin a configuration as shown in FIG. 6. In this case, the signals of thesensors 71, 72, 73 and 74 are transmitted to interface 70, sent tocontrol module 61 and there coded into digital form. Then, the signalsare sent by means of a (not shown) send/receiving apparatus to anothersend/receiving apparatus connected to control module 62. In thesend/receiving apparatuses the signals will be modulated/demodulated.

The above described employment of a non-wired data transmission has theadvantage, that the hardware equipment construction of the apparatuswill be greatly simplified. Regarding a possible disadvantage of saidnon-wire transmission that insecurities might arise, appropriatemeasures can remove this difficulty. For instance, it is possible (inthe embodiment according to FIG. 6) to send with every data transmissionbetween the control module 61 and the control module 62, a n-Bit longcode signal, which is switched in before and after the transmission of adata block. The current receiving control module will only process thereceived data when the code signal, before and after the transmission ofthe data block, has been received without error and is identified.

In this embodiment, indeed the apparatus and programming expendituresfor the control system will be appreciably increased. However, for thisincrease, the practical assembly of the stranding machine will besubstantially simplified, since in this case, principally a current feedfor energy supply between stationary and moving parts must be made.

By means of the new configuration of the stranding machine, it ispossible to use spools, which up to this time could not be installed instanding machines. For an example of such spools, reference can be madeto the spools mention in the descriptions of the PCT/EP93/03404 and thePCT/EP92/02804. These applications show disassembled spools of plastic,which in a very simple and reliable manner can be reassembled into awinding spool. The use of such spools, particularly spools with conicalwinding cores, was not possible in stranding machines up to this time.
